Understanding DPS in Old School RuneScape
This OSRS DPS calculator lets you compare weapons, attack speeds, and special attacks for the most accurate damage estimates. Calculations use your max hit, hit chance, and attack speed, following the same formulas used by the OSRS Wiki and top theorycrafters. Use this tool for combat, bossing, and efficient training.
Tips for Accurate DPS
Use realistic accuracy estimates from your hit chance calculations.
Include specials or DoT as separate multipliers or toggles.
Compare DPS alongside kill speed, AoE and survivability — DPS is only one metric.
OSRS DPS Calculator FAQ
How is DPS calculated? DPS is estimated by multiplying your average hit (roughly half of max hit adjusted by accuracy and specials) by attacks per second (1 / (ticks * 0.6)).
Should I include DoT or bleed? Include DoT as a separate contribution; this tool approximates bleed as a small DPS bonus toggle.
How to estimate accuracy? Use combat formulas or measured hitrates from sample runs.
What about specials? Apply a special multiplier or set exact special logic in future presets.
